Im using Hardy Haron

I have a Linksys wireless card and Im having trouble with it

Broadcom Corporation BCM4306 802.11b/g Wireless LAN Controller (rev 03)
[Needs b43legacy]

Using fw-cutter I have installed b43 and b43legacy

when my computer boots I run the commands

sudo modprobe b43
sudo modprobe b43legacy

The network manager is able to see the network, but is never able to connect

I have exactly the same problem with BCM4306. After installing the B43 firmware, the network manager can see several networks, but cannot connect to any of them.

Can anyone shed any more light on this issue?
